GST New Housing Rebate BC: What First-Time Buyers on New Builds Get Back

One of the most significant differences between buying a resale home and a new build in British Columbia is GST. Resale homes are exempt from the federal Goods and Services Tax. Newly constructed homes, pre-sale condominiums, and substantially renovated properties are not — 5% GST applies to the full purchase price. On a $900,000 new condo, that's $45,000 in federal tax.

Two rebate programs exist to offset this cost. Understanding how they work, who qualifies, and how they interact can mean tens of thousands of dollars in savings on your closing costs.

Why New Builds Attract GST

GST applies to the first sale of a newly constructed residential property in Canada. When a developer sells you a newly built condo or townhouse, that transaction is treated as a commercial supply — the developer is a GST registrant and must collect and remit GST.

Resale homes are different. When you buy an existing home from a private seller, that seller is not a commercial entity making a taxable supply, so GST doesn't apply. This is why a $900,000 resale condo and a $900,000 new condo have fundamentally different tax treatment at closing.

The purchase price on a developer's pre-sale contract may or may not include GST — contracts should specify this clearly. If GST is included in the purchase price, your rebate will be applied against it. If GST is additional (common in commercial practice), you owe the tax on top of the contract price and then claim the rebate separately.

The Original GST New Housing Rebate

The existing federal GST New Housing Rebate has been available for years. It works as follows:

• Homes priced up to $350,000: You receive a rebate equal to 36% of the GST paid, up to a maximum of $6,300.
• Homes priced between $350,001 and $450,000: The rebate phases out linearly from $6,300 to zero.
• Homes priced at $450,001 and above: No rebate is available.

In British Columbia's market, where new condo prices in Metro Vancouver frequently exceed $600,000 or $700,000, this existing rebate is effectively irrelevant — the price threshold wipes it out entirely for most buyers.

The New First-Time Home Buyers' GST Rebate (Bill C-4, 2026)

On March 12, 2026, the federal government enacted Bill C-4, the Making Life More Affordable for Canadians Act, which created a new, separate GST rebate specifically for first-time buyers of newly built homes. This program is retroactively effective from March 20, 2025.

The new rebate operates at much higher thresholds:

Homes priced up to $1,000,000: Eligible first-time buyers receive a 100% rebate of the 5% GST paid, up to a maximum benefit of $50,000.

Homes priced between $1,000,001 and $1,500,000: The rebate phases out linearly across this band. The formula reduces the maximum $50,000 rebate proportionally based on how far above $1,000,000 the purchase price is.

Homes priced at $1,500,000 and above: The rebate is fully phased out — no federal GST relief is available.

This is a dramatically more useful program for BC buyers. A first-time buyer purchasing a new $950,000 condo gets a full rebate of $47,500. A buyer at $1,200,000 gets a partial rebate of approximately $25,000. The coverage extends to the realistic price range for new condos in Surrey, Coquitlam, Burnaby, and similar markets.

Who Qualifies for the Bill C-4 First-Time Buyer Rebate

The eligibility criteria are strict and must all be met:

• You must be at least 18 years of age and a Canadian citizen or permanent resident
• You must not have owned or occupied a property as your primary residence in Canada or anywhere globally during the current calendar year or the four preceding calendar years. This restriction applies to you and your spouse or common-law partner
• You must be the first person to occupy the home after construction or substantial renovation is complete
• Neither you nor your spouse can have previously received this specific GST rebate

The program also contains anti-avoidance rules targeting contracts signed before March 20, 2025 that are later modified, assigned, or cancelled primarily to access the new rebate.

How the Rebate is Claimed

For purchases directly from a developer, the rebate is typically assigned to the developer at closing. This means the developer applies the rebate credit on your behalf and reduces your net GST payable by the rebate amount — you don't pay the full GST and then wait for a refund. The developer signs an assignment agreement with you, submits the rebate claim to the CRA, and the mechanics work in the background.

If the rebate assignment isn't structured into your closing, you can claim the rebate directly from the CRA after closing by filing GST Form 190 for new construction or GST Form 191 for owner-built homes.

Your notary or lawyer should verify that the GST treatment in your contract aligns with your eligibility before you remove subjects.

The Two GST Rebates Don't Overlap — They Stack

The new Bill C-4 first-time buyer rebate does not replace the existing GST New Housing Rebate. They are separate programs. However, because the existing rebate phases out at $450,000 — well below the entry price for most BC new builds — the two programs rarely apply to the same purchase in this market. For buyers at the $350,000-$450,000 range (which applies to some strata units in the Interior or Fraser Valley), both rebates can technically apply, but the interaction is administered through the CRA claim process.

In practice, for most BC first-time buyers purchasing a new condo or townhouse in the $600,000-$1,000,000 range, the Bill C-4 first-time buyer rebate is the relevant program — and it provides the full 100% GST rebate.

Combined Provincial and Federal Tax Savings on a New Build

This is where new construction starts to look compelling for first-time buyers who can make the numbers work. Consider an eligible first-time buyer purchasing a newly constructed townhouse in Surrey at $950,000:

Provincial PTT: Zero, because $950,000 is under the $1,100,000 Newly Built Home Exemption threshold. Saving: approximately $16,500 in PTT.

Federal GST: The 5% GST on $950,000 is $47,500. With the Bill C-4 first-time buyer rebate applying at 100%, the net GST payable is zero. Saving: $47,500.

Total tax saving: approximately $64,000 compared to what you'd owe without exemptions.

The catch is that pre-sale deposits are typically 15-20% spread over 12-24 months, so the cash timeline works differently than a resale purchase. You're managing a deposit schedule rather than a single closing payment. And at completion — often 3-5 years after signing — interest rates may have moved, and your mortgage qualification needs to be confirmed again at then-current rates.
